Acidity of Carbonic Acid
The acidity of an acid depends upon its pH and pKa value. The pKa value of carbonic acid is 6.35, and the pKa value of a compound is inversely proportional to the acidity of the compound. Hence, carbonic acid having a high pKa value is termed under weak acid. Also, the pH range of carbonic acid is 4.68 for 1 mmol/L, 4.18 for 10 mmol/L, and 3.68 for 100 mmol/L, which also shows that carbonic acids are moderately weak acids.
Carbonic Acid (H2CO3)
Carbonic Acid is an inorganic, weak, and unstable acid. The molecule of Carbonic Acid consists of one carbon atom, two hydrogen atoms, and three oxygen atoms. Carbonic Acid is also referred to as a respiratory acid as it is the only acid that is exhaled in the gaseous state by human lungs.
Carbonic acid is studied majorly in various fields of science because of its vast applications and uses. It helps improve marine life due to its natural process of ocean acidification. It is essential for the human body as well. Further in this article, we will learn more about carbonic acids, their structure, their properties, and their uses.
